CHECK RO NIRE FOR CORN PLANTERS.

SPECIFICATION forming part of Letters Patent No. 307,755, dated November11, 1884.

Application filed June 20, 1884.

To all whom it may concern.-

Be it known that I, Austin 0. EvANs, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio,haveinvented certain new and use ful Improvements in Check-Row ires forCorn-Planters, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to that class of checkrow wires which are providedwith equidistant operating-buttons, which serve not only to operate thecheck-row mechanism of the planter, but also to connect the ends of twoadjacent links. Ordinarily the ends of the links within the buttons areconnected to the buttons only, so that the buttons virtually becomelinks themselves and have to bear the tension of the wire.

The novelty. of my invention consists in coupling the links directlytogether and inserting their coupled endsintoa button,which becomesswiveled upon them, serves to pro tect them, and at the same timepermits of their being uncoupled whenever, as is the frequent practicein the field, it is desired to unjoint the wire to carry it around atree or for any other purpose.

I11 the accompanying drawings, Figure 1 is a perspective view of one ofmy improved buttons readyto be applied to the wire. Fig. 2 is acorresponding view with the button applied to the wire. Fig. 3 is alongitudinal central sectional view of the same. Fig. 4 is a transversesectional view of the same.

The same letters of reference are used to indicate corresponding partsin all the ures.

The button A is preferably a malleable shell, with rounded heads a,containing perforations b for the passage of the links of the wire. Itis cut away on each side, as shown, leaving the connecting-pieces c, andhas slots (1 through each head in line with each other and opening intothe perforations b. In Fig. 1 these slots are shown open sufficiently toenable the button to be slipped over the coupled ends of two adjacentlinks, after which, by pressure, they are closed, as seen in Fig. .2, toprevent the accidental removal of the but ton.

The links Bare connected together in the usual way, as seen in Figs. 2and 3.

(No model.)

From this construction it will be seen that the buttons are swiveled onthe links, while at the same time the coupled ends of thelinks areprotected by the button, which encompasses them, and the doubled backends of the loops of the links rest and are confined in the perforationsb of the button, thereby taking the strain off of the ends of the wires,as shown in Figs. 2 and 3, and as will be readily understood.

When it is desired to unjoint the wires at any point, it is onlynecessary to spread open the slots of any of the buttons, remove thesame, and unjoint the wire. The recoupling can be as readily effected.

Having thus fully described my invention, I claim-- 7 l. A check-rowwire whose links are coupled directly together and the ends turned back,as described, in combination with a button enveloping the connected endsof the links and their turned-back ends, substantially as described.

2. A check-row wire whose links are con nected directly together and theends turned back, as described, in combination with a removable buttonenveloping the connected ends of the links and their turned-back ends,substantially as described.

3. A button for check-row wires adapted to envelop and protect thecoupled ends of the links and their turned-back ends, and having endperforations, through which the links and the turned-back ends pass, and1ongitudinal slots opening into said perforations, substantially asdescribed.

4:. A button for check-row wires enveloping and protecting the coupledends of the links and their turned-back ends, and swiveled thereon,substantially as described.

5. A removable button forcheckrow wires enveloping and protecting thecoupled ends of the links and their turned-back ends, and swiveledthereon, substantially as described.

6. In a cheek-row wire, and in combination with the enveloping button,as described, the link-couplings within the button bent back andinserted into perforations in the end of the same, substantially asspecified.
